Application 'filed January 13, 1908. Serial No. Z10,631.

To all whom 'it 'may concer/a.'

Be it known that l, Amin il. Banniiann, a citizen el the United States,residing at Mill V alley, in the county ol Marin and State ofCalifornia, have invented certain-'i new and useful lmproi'feinents inGaseous-lluel Burners, of which the l'ollowin0l is a speci'lication.

My invention relates to improvements in gaseous fuel burners.

rllhe object ol my invention is to provide a gaseous fuel burner whichis simple in con struction and insures perfect combustion in operation.

My invention consists in the novel con struction and combination ofparts shown in the accompanying drawing, described in the followingspecification and claimed in the appended claims.

Referring to the ligures shown in the said drawing Figure 1 is asectional view of the said burner and is also a sectional view oiconnected parts partly broken away. Fig. 2 is a sectionalv view of saidburner taken on lines x-m of Fig. 1.

In the drawings, A. represents the said burner.

2 indicates a tee, 3 a plug supported in one end of said tee and 4 aplug supported in the other end of said tee.

5 shows a tee inclosed in the chamber formed by the tee 2 and the plugs3 and 1l. The tee 5 supports in one end the ilug 6 and in the oppositeend the plug 7, these plugs provided respectively with orilices 8 and 9.The tee 5 is l-ept in its proper position in said chamber by the screws'12, held in apertures in the wall of the tee 2, and by nipple 13secured in the vertical branch of tee 5. The lower end of nipple 13 issecured in elbow lil, and said elbow is supported by tube 15. A circularrod 13 extends centrally through the tube 1 5 and is held in position inthe union 16. The diameter of the rod 18 is less than that of theinterior of tube 15 so that an annular channel is provided between theexterior of said rod and the interior surface ol said tube. A tube 17extends into the side aperture of said union 16 for the supply of gas tothe device which ilows in the annular channel between the rod 18 andinner wall of the tube 15, and thence upward through nipple 13 into thecentral chamber in tee 5, and

thence through the central horizontal channels 3-9 in plugs 6 and 7 intothe respective splaces between the mouths of said central c annels andthe oppositely positioned chan nels 10 and 11, where the meets theascending currents of air entering the aperture between the wall oinipple 13 and tee 2, the discharge oi the consequent burning liuidtalring place through the respective a'iertures 10 and 11. The form otthe apertures 3 and Q is such as to concentrate the volume ol passingtherethrough to secure the most eii'ective result, the center line olsaid apertures 8 and 9 being the center line of said apertures 10 and11, resulting in obtaining more effective combustion. The expulsion ofthe gas into the mixing chamber opposite the oriiices 8 and 9 may beaccomplished by any suitable method known in the art.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is:

1. In a gaseous liuel burner the combination of a tee, plugs havinglongitudinal aper tures extending therethrough secured in the lateralbranches oi' said tee, a tee secured in the central chamber of saidfirst named tee, plugs having longitudinal apertures extend-` ingtherethrough secured in the horizontal branches of the tee in saidchamber, a tubular nipple secured in the vertical branch of thelast-named tee, a horizontal supply pipe connected to the lower end ofsaid nipple, a longitudinal rod of less diameter than the interior ofsaid supply pipe positioned therein and out of contact with the innersurface of said pipe, and a supply pipe connected to the last-named pipeand delivering therein, substantially as described.

2. in a gaseous fuel burner the combination of a tee, plugs havinglongitudinal apertures extending therethrough secured in the lateralbranches of said tee, a tee secured in the central chamber of saidiirst-named tee, plugs having longitudinal apertures extendingtherethrough secured in the horizontal branches of the tee in saidchamber, said apertures being outwardly contracted, a tubular nipplesecured in the vertical branch of the last-named tee, an elbow and ahorizontal pipe connected to thelower end of said nipple, a longitudinalrod of less diameter than the interior of said horizontal pipepositioned therein and out of contact with the limer surface of saidpipe, and a supply pipe con nected to the last-named pipe and deliveringtherein, substantially as described.

3. In a gaseous fuel burner the combination of a tee, plugs havinglongitudinal apertures extending therethrough secured in the lateralbranches of said tee, a tee centrally positioned in the chamber of thefirst-named tee, plugs having longitudinal apertures extendingtherethrough secured in the horizontal branches of the tee in saidchamber, said apertures being outwardly contracted and being inalineinent with the apertures of the outer plugs, a tubular nipplesecured in the vertical branch of the last-named tee, an elbow andhorizontal pipe connected to the lower end of said nipple, a tubular rodof less diameter than the interior ol said horizontal pipe positionedcentrally therein whereby an annular equidistant chamber is formedbetween the exterior of said rod and the inner' surface of said pipe,and ineans secured to said pipe for delivering the supply through saidchamber.

4. In a gaseous fuel burner, the combination of a tee, plugs havinglongitudinal apertures extending therethrough secured in the lateralbranches of said tee, a tee centrally positioned in the 'first-mentionedtee, plugs hav ing longitudinal apertures extending therethrough securedin the lateral branches of the second-named tee, the apertures in saidplugs bein "interiorly wider and exteriorly narrower, t e lower branchol said iirst mentioned tee being open, a vertical supply pipe connectedto the lower branch of the inner tee, a horizontal supply pipe connectedto said vertical supply pipe, and a rod arranged within said horizontalsupply pipe and out of Contact with the inner surface of said pipe.
